I know there are several threads on this issue, and I have read every single one that I can find. But, haven't been able to fix the issue yet. 1997 LC. Left blinker blinks twice as fast. The left rear bulb does not flash. No LED bulbs anywhere. The problem started about 3 months ago, but was intermittent. It's been consistent for the past ~5 weeks now.
Here is what I've done.
0. (In all the steps below I've applied permatex dielectric to each connection/socket along the way)
1. Replaced both front and back bulbs (non-led) bulbs on the left side. Same issue.
2. Verified both of the new bulbs worked, by putting them into the right blinkers.
2. Swapped the bulbs from the right blinkers (which work fine) into the left blinkers. Same issue.
3. Replaced the blinker relay behind the dead pedal (not fun) with a new OEM one from the dealer. Same issue.
4. Disconnected, cleaned (wire brush) and applied dielectric grease to all 3 of the ground connections. (EA, EB and BG in the EWD manual. Pages 30 and 36).
5. Checked the connections in the left rear panel (where the jack and tools are stored). When I say "checked" I mean I disconnected each of the connectors, looked for corrosion, applied some dielectric, and reconnected.
6. Disconnected the trailer hitch wiring harness behind the spare tire. Had trouble finding specific documentation for this, but the connector I disconnected is linked below. This connector was super corroded inside, and when I disconnected it, neither the left or right rear blinkers worked. I cleaned out the connector as best as possible, applied dielectric, and reconnected. Nothing changed. Is there a way to fully disconnect the trailer wiring upstream in the left rear panel where the tools/jack are stored?

7. I have ordered the tiny blinker lights for the rear-side blinkers, but I don't think these are the cause. I wasn't even aware there were bulbs in there, and neither side has worked since purchasing this vehicle. Plus the right side is also burnt out, and isn't causing the right blinkers to fail.
8. Took out the multimeter (not my forte), and tested the right side (which works) and was getting 0/12/0/12/0 volts when blinking. The left side (not working) was getting 0/1.6/0/1.6 volts, which I'm assuming means I have a bad ground somewhere.
I've also been looking for worn wires along the way, but haven't seen any. My guess is this is related to trailer wiring, but not sure what to do next. I need to pass a state safety inspection in about a month, so I obviously need to figure this out asap.
Thanks for any help you can provide.
